Hi guys, I purchased both pairs of these cans because I was in need of some new sound! I have been researching a solid portable amp that I can use at home and on the go, I have looked a lot into the JDS Labs CMoyBB and the c421. But I was curious if there was anything else that's really good that I haven't pondered? Preferably looking at something under $150.

Thanks!
